This work presents an architecture to help designing and deploying smart mobility applications. The proposed solution builds on the experience already matured by the authors in different fields: crowdsourcing and sensing done by users to gather data related to urban barriers and facilities, computation of personalized paths for users with special needs, and integration of open data provided by bus companies to identify the actual accessibility features and estimate the real arrival time of vehicles at stops. In terms of functionality, the first “monolithic” prototype fulfilled the goal of composing the aforementioned pieces of information to support citizens with reduced mobility (users with disabilities and/or elderly people) in their urban movements. In this paper, we describe a service-oriented architecture that exploits the microservices orchestration paradigm to enable the creation of new services and to make the management of the various data sources easier and more effective. The proposed platform exposes standardized interfaces to access data, implements common services to manage metadata associated with them, such as trustworthiness and provenance, and provides an orchestration language to create complex services, naturally mapping their internal workflow to code. The manuscript demonstrates the effectiveness of the approach by means of some case studies.

Model View

CLOUD is an elision of Common Location-independent Online Utility available on-Demand and is based on Service Oriented Architecture (SOA). Today a chunk of researchers were working towards contrivance based on multi-tenant aware Software as a Service (SaaS) application development and still a precise pragmatic solution remains a challenge among the researchers. The first step towards resolving solution is to enhance the virtual scaffold and propose it as a System under Test (SuT). The entire work is proposed as a Model View Controller (MVC) where the tenant login through the View and write their snippet code for encapsulation. The proposed VirScaff schema acts as Controller and provides authentication and authorization by role/session assignment for tenant and thus helps to access data from the dashboard (Viz., Create, Read, Update and Delete (CRUD)). The SuT supports and accommodates both SQL and Not only Structured Query Language (NoSQL) dataset. Finally, this paper construed that SuT behaves well for both SQL and NoSQL dataset in terms of time and space complexities. To sum-up, the entire work addresses the challenges towards multitenant aware SaaS application development and highly commendable while using NoSQL dataset.

International audience Spatial Metadata are used to describe the existing data sources in order to facilitate their access and sharing between different actors. The problem of exploitation of these metadata arises when they should be catalogued within the framework of a platform for spatial data federation. We describe a service oriented approach for structuring this component, with an implementation based on LDAP. To achieve this, we start from a canonical language that unifies the major known geographic metadata standards, and then we define new classes of LDAP objects which map syntactic units of canonical language.

Enterprise Integration enables the sharing of information and business processes among the various applications and data sources within and beyond an organization. Over the years, due to changes in business requirements and availability of sophisticated technology, the architectures for integrating applications and data sources have evolved from simple point-to-point integration technique to more comprehensive architectures leveraging Service Oriented Architecture (SOA) and Event Driven Architecture (EDA). In this chapter, the authors trace this evolution, and examine the architectures in terms of complexity versus business benefit. The architectures are presented in a logical progression starting with the simplest form.

Web is a place for information sharing as well as service providing. With the addition of Service Oriented Architecture ensures better reusability, maintainability and flexibility among the heterogeneous data sources. Possibility of a better interoperability within such a heterogeneous data sources is less without further assistance. For better service discovery, these issues must be cleared first. Besides this, security measures also play a key role. By developing a Multiagent based middleware system can resolve all these issues. Further it will add up better communication among the different modules of the system as well as the self learning capability. This paper’s approach is aimed to the development of Multiagent system based middleware architecture for better service discovery, selection and invocation through a secure way without replacing the existing services based on Web Service and Semantic Web Service technologies. The architecture will use ontologies heavily to introduce the rich semantics to the services to provide better meaning understandable by machines.
